Product Description
Service Process for Black Hard Anodized CNC Machined Aluminum Lens Barrels
1. Pre-Production Collaboration
(1) Requirement Confirmation
Confirm lens barrel application, outer and inner diameters, length, thread specifications, concentricity requirements, surface finish, anodizing color and thickness, order quantity, and delivery timeline.
(2) Drawing & Data Review
Review 2D technical drawings or 3D CAD models including internal bore tolerances, thread standards, and optical alignment requirements.
(3) DFM & Tolerance Analysis
Analyze machining feasibility, concentricity control, and thread accuracy to ensure proper lens alignment and assembly compatibility.
2. Process Planning & CNC Machining
(1) Material Selection
Select aluminum alloys such as 6061-T6 or 6063 based on dimensional stability and surface treatment suitability.
(2) CNC Programming
Develop CNC turning and milling programs to machine internal bores, external profiles, and precision threads in controlled sequences.
(3) Machining Simulation
Simulate machining processes to minimize deformation and ensure consistent wall thickness and dimensional accuracy.
3. Production & Quality Control
(1) Precision Machining
Perform CNC machining to achieve smooth internal bores, accurate threads, and tight concentricity control.
(2) Dimensional Inspection
Inspect inner diameter, outer diameter, thread fit, and coaxiality using precision measuring instruments.
(3) Surface Preparation
Conduct fine deburring and surface preparation prior to anodizing to ensure uniform coating quality.
4. Surface Treatment & Delivery
(1) Black Hard Anodizing
Apply hard anodizing with black finish to improve wear resistance, surface hardness, and light absorption performance.
(2) Cleaning & Protection
Clean parts to remove residues and protect anodized surfaces to prevent scratches during handling.
(3) Packaging & Delivery
Package lens barrels individually or in custom trays. Deliver according to agreed logistics arrangements.
